:EPACKING,

To all whom it may concern: Be it known that I, FRANK HENN a citizen" of the United States, residing at Chicago, in the county of Cook and State of Illinois. have invented certain new and useful Improvements in Packing, of which the following is aspecification. [@One of the objects of this invention is to, d metallic packing 1 for: packing piston rods chine elements.v I V Another object-of the invention is to provine means for securing the packing in operative relation to the part to be packed/ A further object of the invention is to provide means for applying. metallic packing to machines not, originally intended to receive such packing. y In the accompan -iing draw ngs, Figure 1 is a sectional View illustrating an embodiment of my invention, the View being taken on the planeoi dotted line 1 l of Fig. 2. Fig. 2 is a sectionpn dotted line 2 2 of Fig. .igs. 3. {and 5 are perspective detail iews of indii'idual, packing sections. Fig. 6 is a detail viewof, a spring for holding the packing in contact with the moving element.

The packing material comprises a plural- .of contractible rings of suitable ackin'g "have shomithree such rings, the twoend rings being similar and the intermediate or filler ring assuming a special form.

eetea, 1908. .i'

ReferringtoFi'g. 2 it will'be seen that the end rings coinprisea number of'curved segments or' links 7 flexibly connected together, as, for example, by means of a knuckle 8- upon one endi of each link, said knuckle being adapted to lie within a socket 9 formed on the opposite end of each link. I'have herein shown three such links flexibly connected together, the spaces between the adjacent ends of said series being lapping members 10 and.

11 adapted to permit the ring formed by the members 7 and filled by two ov'er- I said overlapping members to contract as said members wear away. The member 10 upon the adj acent link 7. Upon" one end of the member 11 is a knuckle 13 fitting within the'socket 9 of the adjacent The member 10 is made tapering its outer side to contact the similarly curved surface of the member 11 Onthe free end of the member 11 and at the points-of connection between the members '7, 10 and 11,: projections 14 are formed, against hereinafter described. I

The intermediate or filler ring constituted by the segments 1'5"(Fig. 5) has open spaces therein between the adjacent ends of said' segments to permit said filler ring to contract as its inner surface is worn away. Each of the segments 15 is provided on its outer side with a projection 16 upon which bears the spring hereinbefore alluded to.

The means shown in Figs. 1 and 2 for holding the packing rings in fluid-tight contact. withthe moving part B consists of a spring 17 in the form of a closed loop or circle. When in its unfiexed position, the spring 17 and 11 in contact with the moving part B I may provide a special leaf spring 19, the springs 17 and 19 being secured together and to the packing by means oi a pin 20. As a further means for contracting thefiiac'king rings into fluid-tight contact with the moving part B a leaf spring 21 may be interposed between; the inner annular wall of the member C and said packing rings.

In lieu of the springs shown in Figs. 1,- 2 Y and 6, I may use a coiled spring 22 wound about the packing material, as shown in Fig.

, counter-bore 28 7 the ends of said spring" being secured in place in any suitable way.

In an engine especially designed to receive metallic packing the stuffing box may take the form shown in Fig. 7. The cylinder head 23 is rovided with an annular recess24 surg the opening 25 through which the iston rod B passes. The packing is connned in said recess by means comprising a collar 26 having an annular flange 27 fitting within and forming a ground joint with a in the cylinder head. The collar 26 is secured to the cylinder head by means of the stud bolts 29-and nuts '30. adjusting ring 31 has a screw-thread connection with the collar 26.

In use, as the inner. sides of'the packingsections 7, 10v and 11 wearaway the springs 17, 19 and 21 keep said sections in fluidthe end rings contract.

I claim as my invention: a

1. Metallic packing comprising a series of segments flexibly connected together, and two overlapping sectionsconnected to the opposite ends of said series.

2. Metallic packing comprising a series of segments arranged end to end, and two overlapping sections interposed between the ends of said series.

3. A metallic packing segment having a pivot knuckle at one end and a socketat' the other adapted to receive a similar knuckle.

4. A metallic-packing segment having a knuckle at one end, a socket at the other end,

with the moving part. Th'e sections 10 and 11 slide over one-another as some? and a projection at the last mentioned end on the outer side of the segment.

5. A metallic packing segment having a central bearing projection on its outer side. I 6. A metallic pacln'ng section having a knuckle at one end and 7. A metallic dpacking segment having a socket at one en ment tapering to a point, the inner and outer sides of said segment being curved'on the arcs of circles, said curves attending to said point.

8. Packing comprising a jointed spl'" the ends of said ring overlapping, an annular spring bearing upon the joints of said ring, and a spring connected at one end to said annular spring and upon said overlapping ends.

, 9. Metallic packing comprising three similar segments, each having a knuckle at one end and a socket at the other end. the

knuckles of two of said segments lying in the '1 sockets of adjacent segments; a segment having a socket at one end adapted to receive the knuckle of one of the first men tioned segments; a segment having a knuckle adapted to lie in the socket of one of the first mentioned segments, the two last mentioned segments being adapted to overlap; and means for holding all of said segments in contact with the part to be packed.

10. Packing comprising a joint-ed split ring, the ends of said ring overlapping, an annular spring bearing upon the joints in said ring, and a spring bearing upon said overlapping ends.

11. Packing comprising a split ring, the

ends of said. ring overlapping, an annular spring tending to contract said ring, and a spring bearing upon the split side or portion of said ring.

12. A packing-containing structure comprising an annular member having an inwardly-extending packing-supporting flange, a ring having a screw-thread connection Witl'i said annular member, and means for preventing rotation of said ring.
